Abstract
Effects of the Ga-As soft laser on clinically oral-isolated Streptococcus
mutans and on temperature changes of the finger pad and ear lobe skin and tongue mucosa were studied. Bacterial suspensions of S. mutans were placed on solid blood agar plates. The center of the plates was subjected to 3-min laser treatment every 24 h during a six-day period. Then the bacteria from the target area were maintained on a new plate and examined for survived bacteria. The use of the laser on the agar plate surface produced no bacterial or bacteriostatic effect. Additionally, temperature changes of the ear lobe skin and finger pad skin and tongue mucosa during and after laser treatment were not significantly different from the control values.
